CHURN.

SPECIFICATION forming part of Letters Patent No. 271,266, dated January 30, 1883.

Application filed Muy 18, 18S-2. (Model.)

To LH whom it may concern.:

Be it known that I, DANIEL K. POMEROY, of Ottawa, in Province ot' Ontario and Do minion of Canada, have invented certain Improvements in Ghurns, of which the following is a specification. 1

My invention relates to oscillating churns; and it consists in a novel mannerof'constructing, hanging, and operating the same, as hereinafter fully set forth.

In the accompanying drawings, Figure 1 represents a perspective view, and Fig. 2 a vertical longitudinal central section, of. the churn.

The objects ot my invention are to render theoperation of the churn easier than under former constructions, to causethebody to hang naturally in a horizontal position instead ot' tipping, and to produce a motion which shall cause the butter particles to be readily' separated from the cream or milk. To this en d I construct my churn as shown in the accom panying drawings, in which- A represents a stoutframe, consisting of uprights a, inclined braces b, and cross ties or braces c, which may be put togetherin any approved manner, but preferably arranged as shown.

` B represents a rock-shalt, jonrnaled in the upper ends ofthe uprights a, and C the churn body or vessel suspended from the rock-shaft B by links or rods D passing through said rock-shaft and bent at'their lower ends to forni journals d, which pass through ears c formed by the projection above the body of barsf secured to the sides thereof. By this arrangement of paris it will be seen the body is free to swing back and forth, with the rock-shaft B as a center ot'motion, and also to rock or tip upon the joints or journalsf, thereby securing a compound motion. By thus passing the rodsthrough the rock-shaft,instead of forming a joint and employing a stationary cross-bar, I avoid any side play of the churn-body.

For the purpose of imparting to the churn the compound motion noted Iprovide theframe with arms or brackets E, secured firmly to the uprights a, and carrying a crank-shaft, F, the

duces both a rocking anda swinging` motion ot' the body, which body is of the form and construction shown in Fig. 2. By referring to said figure the body will be seen'to consist of vertical sides h, a flat bottom, i, and rounded ends formed by a series of flat-faced strips,j, meeting` each other at a slight angle. The top is formed with an opening, 7c, closed by a cover, H, and at each side ot' the opening there is placed an inclined board or deector, l, which serves to direct tlIe cream downward away from the opening. The cream is caused by the operation of the churn to travel along the bottom ot' the body, follow the contourot' the end, and thereby pass to the top ot' the body, and thence to be thrown bythe deiiector down to the bottom again, when the travel is repeated but in areverse direction. In traveling over the successive flat faces of the ends the body is broken up andca'used to roll over and over-a result which is found in practice to be highly conducive to a rapid separation of the butter particles.

I am awarethat churn-bodieshave been pro'- vided with rounded ends and also with square ends, and that such bodies have been suspended by rods vor bars and given a compound motion by the rotation of a crank-shaft; but so far as I am aware no one has ever before located the joints or journals by which the body from that produced by arranging the pivotsl below the top ofthe body, as under my arrangement the body is moved endwise in rocking or tipping upon the pivots, and under the other arrangementmentioneditsimply rocks without moving endwise. The difference is found in practice to be very considerable, asitinsures a more certain travel of the cream upward around the ends. The operation of the churn under this arrangement is also much easier than under the former plan, since the tendency to assume a horizontal position causes the body to raise or assist in raising itself at the end of its movement in either direction.

Having thus described my invention, what I claim is- 1. The herein-described churn, consisting of naled in said frame, rods 1), 'passing through 1o frame A, body C, suspended by links or rods said rockshaft, and the body O, provided with D, pivoted to ears projecting above the body, ears projecting above the body and jointed as shown and described, and crank-shaft F, to the rods D, all as shown and described.

5 journaled in the frame and connected with the body, said parts being combined and arranged l DANIEL K' POMEROY' to operate substantially as set forth. Witnesses:
